While the Windows 10 Creators Update is set to start rolling out to desktop PCs on April 11, Windows 10 Mobile users will start seeing it roll out a bit later on April 25.
Though we knew the Mobile rollout was likely to occur later than desktop, there was no firm date before. Microsoft has now confirmed April 25 as the Mobile rollout date in a new blog post on the Creators Update desktop release:
Windows Phone will follow the same phased approach, with rollout scheduled to begin April 25. Note that update availability may vary by manufacturer, model, country or region, mobile operator or service provider, specific installed software, hardware limitations and other factors such as feedback from customers.
Because of the phased rollout schedule, not everyone will see the update arrive on day one. Given the somewhat slow rollout that we saw with the Anniversary Update, it could be some time before all devices eligible for the update receive it.
Aside from the note on the Mobile release date, Microsoft has also given us a bit of good news for those eager to get their hands on the Creators Update for desktop earlier than April 11. For anyone who wants to take the dive, Microsoft says you can start manually upgrading to the Creators Update on April 5 through the Update Assistant.
